Temporal externalists argue that ascriptions of thought and utterance content can legitimately reflect contingent conceptual developments that are only settled after the time of utterance. While the view has been criticized for failing to accord with our “ordinary linguistic practices”, such criticisms (1) conflate our ordinary ascriptional practices with our more general beliefs about meaning, and (2) fail to distinguish epistemically from pragmatically motivated linguistic changes. Temporal externalism relates only to the former sort of changes, and the future usage relevant to what we mean reflects reason-driven practices that are rational for us to defer to.

It has become increasingly popular to suggest that non-individualistic theories of content undermine our purported a priori knowledge of such contents because they entail that we lack the ability to distinguish our thoughts from alternative thoughts with different contents. However, problems relating to such knowledge of 'comparative' content tell just as much against individualism as non-individualism. Indeed, the problems presented by individualistic theories of content for self-knowledge are at least, if not more, serious than those presented by non-individualistic theories. Consequently, considerations of self-knowledge give one no reason to embrace individualism. If anything, they give one reason to reject it

Those sympathetic to the naturalistic side of James hope that his critique of ‘philosophical materialism’ can be separated from those elements of his thinking that are essential to his pragmatism. Such a separation is possible once we see that James’s critique of materialism grows out of his views about its incompatibility with the existence of objective values. Objective values (as James understands them) are incompatible, however, not with materialism in its most general form, but rather with materialism that understood the ‘material world’ in terms of the sciences of the late nineteen hundreds. In particular, one could not defend the potential objectivity of value in the way that James hoped if one endorsed the particular ‘pessimistic’ cosmology characteristic of the sciences at the turn of the last century. Consequently, if one rejects certain ‘empirical assumptions’ associated with the science of James’s day, the possibility of a type of ‘melioristic materialism’ opens up, and this sort of materialist could still understand value in the way that James proposes.

Akeel Bilgrami has always argued that the contents of our thoughts are constitutively constrained by what we could be said to know about them. In earlier work he explained this in terms of a connection between thought and rationality, but his recent book argues that the ultimate ground for self-knowledge rests in our notion of responsibility. This paper will examine these arguments, and suggest that if Bilgrami is right about how self-knowledge is grounded, then it need not constrain our content ascriptions as thoroughly as he once proposed that it must.

NB: This paper has been largely displaced by my: “Externalism, Metasemantic Contextualism and Self-Knowledge”, in Goldberg, (ed.) Externalism, Self-Knowledge and Skepticism. New York: Oxford University Press, 2015, pp. 228-247. // While straightforwardly ambiguous words like “bank” and obviously indexical words like “I” are unproblematically treated as referring to different things in different contexts, such variations are displayed by terms that seem neither ambiguous nor indexical. This paper will argue that traditional accounts of word meaning (in which a single fixed meaning is attached to each entry in one’s ‘mental lexicon’) have problems accounting for how the referent of a non-ambiguous/non-indexical term can shift from context to context, while a moderate version of semantic holism can do so by understanding the comparative weight of the meaning-constitutive beliefs as itself something which can vary from context to context.

'Epistemic' theories of vagueness notoriously claim that (despite the appearances to the contrary) all of our vague terms have sharp boundaries, it's just that we can't know what they are. Epistemic theories are typically criticized for failing to explain (1) the source of the ignorance postulated, and (2) how our terms could come to have such precise boundaries. Both of these objections will, however, be shown to rest on certain 'presentist' assumptions about the relation between use and meaning, and if allows that the meaning constitutive elements of our linguistic practices can extend into the future, the possibility of a new sort of 'normative epistemicism' emerges

'Interpretational' accounts of meaning are frequently treated as incompatible with accounts stressing language's 'social' character. However, this paper argues that one can reconcile interpretational and social accounts by distinguishing "methodological" from "ascriptional" individualism. While methodological individualism requires only that the meaning of one's terms ultimately be grounded in facts about oneself, ascriptional individualism requires that the meaning of one's terms be independent of how others use theirs. Interpretational accounts are committed only to methodological individualism, while arguments for languages social character are best understood as attacks on ascriptional individualism. As a result, one can recognize language's social character and still be an interpretationalist

Our ascriptions of content to utterances in the past attribute to them a level of determinacy that extends beyond what could supervene upon the usage up to the time of those utterances. If one accepts the truth of such ascriptions, one can either (1) argue that subsequent use must be added to the supervenience base that determines the meaning of a term at a time, or (2) argue that such cases show that meaning does not supervene upon use at all. The following will argue against authors such as Lance, Hawthorn and Ebbs that first of these options is the more promising of the two. However, maintaining the supervenience thesis ultimately requires understanding the relation between use and meaning as 'normative' in two important ways. The first (more familiar) way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between correct usage and actual usage. This first type of normativity is accepted by defenders of many more temporally restricted versions of the supervenience thesis, but the second sort of normativity is unique to theories that extend the supervenience base into the future. In particular, if meaning is partially a function of future use, we can understand other commitments we are often taken to have about meaning, particularly the commitment to meaning being 'determinate', as practical commitments that structure our linguistic practices rather than theoretical commitment that merely describe such practices.

This paper is concerned with Davidson's argument that very general properties of the theory of interpretation make the skeptical claim that most of our beliefs could turn out to be false insupportable. Conceived as a 'straight' answer to the skeptic Davidson's argument is not especially convincing. In particular, Davidson's answer to the skeptic presupposes a framework that allows for a new and seemingly more radical skepticism according to which we might not even have beliefs at all. Nevertheless, there is a sense in which Davidson's account of content remaps the conceptual terrain in a fashion that absolves us of the need to rule out the scenarios the skeptic describes. The paper will both present the problems Davidson's position has as a 'straight' solution to skepticism, and discuss the way in which his externalism does weaken the strength of the skeptical challenge.
